I acquired a nice SB-220 in a trade and needed a TX Line Buffer, I went in the kitchen and made a ham sandwich to empty the lunch meat container that I used for my project box.

Any kind of sandwich you choose to make will obviously be a HAM sandwich.

Make sure you have a diode and a small cap across the coil so you don't zap the pass transistor in your Flex.
